Coastal Treatment Plant Export Sludge Force Main Replacement
Document Type
EIR - Draft EIR

Document Description
Note: Extended Review per lead The proposed project involves the replacement of approximately 16,600 feet of two 4-inch ductile iron pipelines which run along the eastern side of Aliso Creek in Orange County. These pipelines convey wastewater sludge from one wastewater treatment plant to a regional facility. The proposed project would replace the existing force mains with a single 6-inch force main made of high density polyethylene (HDPE). The replacement pipeline would follow the route of existing buried utilities within the County of Orange Aliso and Wood Canyons Wilderness Park. The new pipeline would be constructed at a depth of approximately four feet.
